摘要
对湖南省湘西自治州的细叶桢楠进行调查,并选取优良的细叶桢楠单株进行生长性状和材质性状的测定。结果表明:(1)细叶桢楠寿命较长。(2)细叶桢楠基本密度在0.483 2~0.620 9 g/cm3之间,纤维宽度在26.80~33.85μm之间,纤维长度在1.013 0~1.180 3 mm之间。(3)细叶桢楠基本密度与树龄、胸径和材积呈显著正相关关系,在生产上可以通过培育大径材提高基本密度的数值。
Based on the investigation of Phoebe zhennan resources in Xiangxi Autonomous Prefecture, Hunan Province, the growth per- formance and wood property of the selected superior individuals were analyzed. The results showed that ( 1 ) Phoebe zhennan had a long life span. (2) The basic density of Phoebe zhennan was 0.483 2 ~ 0.620 9 g/cms, the fiber diameter was 26.80 ~33.85 μm, and the fiber length was l. 013 0 ~ 1.180 3 mm. (3) Basic density was positively correlated with tree-age, DBH and volume, which indicated that wood basic density could be improved by fostering woods with larger DBH.
